New water cycle on Mars discovered

Approximately every two Earth years, when it is summer on the southern hemisphere of Mars, a window opens: Only in this season can water vapor efficiently rise from the lower into the upper Martian atmosphere. There, winds ...

Life Without Water?

On Saturn’s giant moon Titan, it is so cold that water is frozen as hard as granite. And yet there is a complete liquid cycle of methane and ethane. Scientists wonder whether there could also be life.

Satellite study finds major shifts in global freshwater

A new global, satellite-based study of Earth's freshwater distribution found that Earth's wet areas are getting wetter, while dry areas are getting drier. The data suggest that this pattern is due to a variety of factors, ...

Atmospheric warming altering ocean salinity

The warming climate is altering the saltiness of the world's oceans, and the computer models scientists have been using to measure the effects are underestimating changes to the global water cycle, a group of Australian scientists ...

Deep diving scientists discover bubbling CO2 hotspot

Diving 200 feet under the ocean surface to conduct scientific research can lead to some interesting places. For University of Texas at Austin Professor Bayani Cardenas, it placed him in the middle of a champagne-like environment ...

Water supersaturation in the Martian atmosphere discovered

(PhysOrg.com) -- New analysis of data sent back by the SPICAM spectrometer on board ESA's Mars Express spacecraft has revealed for the first time that the planet's atmosphere is supersaturated with water vapour. This surprising ...

Supersonic winds, rocky rains forecasted on lava planet

Among the most extreme planets discovered beyond the edges of our solar system are lava planets: fiery hot worlds that circle so close to their host star that some regions are likely oceans of molten lava. According to scientists ...

The greening of the Earth is approaching its limit

When plants absorb this gas to grow, they remove it from the atmosphere and it is sequestered in their branches, trunk or roots. An article published today in Science shows that this fertilizing effect of CO2 is decreasing ...

Water cycle

The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Since the water cycle is truly a "cycle," there is no beginning or end. Water can change states among liquid, vapor, and ice at various places in the water cycle. Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go.
